Question
Chapter 13, Problem 1AWK
Summary Introduction
To review:
The level of hormone concentration if the appropriate receptors were absent.
Introduction:
The appropriate level of hormones is to be maintained in the blood to acquire the desired effect on the body. The negative feedback loop helps in maintaining internal homeostasis by keeping the blood hormonal levels in check. It is essential to maintain the rate of secretion of the hormone to maintain the just right levels in the blood, otherwise certain negative effects and disorders may result.

If a hormone interacts with a membrane-bound receptor, then the cell’s DNA will be stimulated to synthesize and secrete a protein.
True or False?
In the 1950s, Earl W. Sutherland, Jr., and his colleagues carried out pioneering experiments to elucidate the mechanism of action ofepinephrine and glucagon. Given what you have learned in this chapter about hormone action, interpret each of the experiments described below. Identify substance X and indicate the significance of the results.(a) Addition of epinephrine to a homogenate of normal liver resulted in an increase in the activity of glycogen phosphorylase. However, when the homogenate was first centrifuged at a high speed and epinephrine or glucagon was added to the clear supernatant fraction that contains phosphorylase, no increase in the phosphorylase activity occurred.(b) When the particulate fraction from the centrifugation in (a) was treated with epinephrine, substance X was produced. The substance was isolated and purified. Unlike epinephrine, substance X activated glycogen phosphorylase when added to the clear supernatant fraction of the centrifuged homogenate.(c)…
Signals carried by hormones must eventually be terminated. Describe several different mechanisms for signal termination.
